Complete the following statements with an appropriate word / term to be filled in the blank space(s).A compass needle is a ________ magnet : super small big fieldless None 2. What kind of magnet is used in a magnetic compass ? temporary magnet none of the above permanent magnet electromagnet None 3. What is the circular enclosure that the magnetic compass is placed in ? stainless steel case nickel case iron case aluminium case None 4. The marked end of a compass needle always points directly to A magnet's south pole Earth's geographic South Pole Earth's geographic North Pole A magnet's north pole None 5. The N-pole of a compass points to the .............. pole of a permanent magnet north north-east south-east south None 6. Which effect of force is caused by the magnetic force between a magnet and a magnetic substance? Change of physical state. Change of position. Change of chemical nature. Change of shape. None 7. How is a compass used to find directions? When suspended freely the compass needle starts rotating in a particular plane and the axis of rotation perpendicular to the plane gives us north and south poles When suspended freely the compass needle aligns itself in the north-south direction which gives us the direction of the north and south poles When suspended freely the compass needle aligns itself in the vertically up-down direction which gives us the perpendicular direction to the needle as north and south poles When suspended freely the compass needle aligns itself in the east-west direction which gives us the perpendicular direction to the needle as north and south poles None 8. Which of the following will help demagnetizing a magnet ? Cooling it Hammering the magnet Putting it in the water Putting in contact with iron None 9. Which of the following is not attracted by a magnet? cobalt nickel bronze steel None 10. The presence of magnetic field at a point can be detected by strong magnet ammeter a compass needle galvanometer None 11. Which types of magnet have two poles close to each other? Bar magnet Horse-shoe magnet Electromagnet Cylindrical magnet None 12. Magnetic strength of the magnet is Concentrated at one of the poles of the magnet Concentrated in the centre of magnet Distributed uniformly throughout the magnet Concentrated at both the poles of the magnet None 13. The answer to which of the following options will distinguish between a magnetic material and a non-magnetic material? Does it affect the direction in which a compass needle points? Is it a conductor or an insulator? Can it be given an electric charge? Is it a metal of a non metal? None 14. How will hammering a bar magnet affect Its magnetic strength? None of the above Is likely to increase Is likely to decrease Will not change None 15. A marine compass is used to determine dip at a place determine direction determine H compare magnetic moments None 16. Which shape of magnet is used in electric bell? Cylindrical magnet Bar magnet Ball-ended magnet Horse-shoe shaped None 17. _______ is the surest test of magnetism. No change Repulsion None of the above Attraction None 18. The device used by sailors and navigator to know the direction is called Speedometer Wind vane Direction finder Magnetic compass None 19. The end of a free hanging magnet which points towards North is called North pole East pole West pole South pole None 20.
